We students have been asking about our opinions on opening iPad classrooms. I am in the favor of this plan for the following reason. To begin with, everyone learns different and everyone can get an iPad with many materials that fits his level and learning style. Moreover, getting online, students can talk teachers and classmates easily. We can learn a lot much conveniently than ever. Besides, paper is no longer a necessity, but it is environmentally﹣friendly to open iPad classrooms. Most importantly, students are interesting in this new way of learning. I hope our school can take their idea into consideration and I am looking forward to attending an iPad class.

High school bullying (霸凌) is generally one of the most 1.(misunderstand) forms of bullying.

This is partly because bullying in high school can take more hidden forms 2. the schoolyard shoving(推搡) normally 3.(associate) with middle school and junior high bullies, and partly because of the fact 4. the older students get the less likely they are to report bullying.

That's a pretty 6.(depress)reality that our children are facing every day and sadly schools and communities continue to fall short when it comes to 7.(battle) the problem of bullying.

Unfortunately, ever since the arrival of the cyber age, bullying has now spread to the Internet, 8. bullies can have a much larger audience for their methods while taking advantage of the ability 9.(remain) anonymous (匿名). This can make the resulting damage much more painful and 10.(hard)to fight.

    China has been the birthplace of many of the world's greatest inventions. It was, for example, the first country to produce paper money. Before the invention of paper money and coins, people used many different kinds of things for buying and selling. 1. This exchange of goods and services for other goods and services is called bartering.

2. In 1200 BC, people in China began to use shells (贝壳) as money. Usually the shells used as money were very small. This made it easier for people to carry money over long distances, and allowed for trade to develop between different parts of the country.

In the years which followed this invention, many other countries around the world began to do the same. 3.

The next development was in 1000 BC, when China started making bronze and copper shells. It wasn't long before the Chinese made round coins out of metal. 4. By 500 BC, metal coins had begun to appear in countries like Persia and Greece, and later in the Roman Empire.

About 1,000 years later, leather was used as money in China, and in 806 AD, the first paper banknotes were produced by the Chinese people. 5.

A.People also began collecting foreign coins as souvenirs.

B.During that time, for example, buying a chicken might cost several potatoes.

C.It was still many years before paper currency appeared in Europe.

D.However, as economies developed, such exchanges became impractical.

E.They also used tiny shells as money for buying and selling.

F.As time went by, trade between countries increased.

G.The first coins often had holes in them so that people could string them together.

    The third﹣generation hybrid rice which was developed by Yuan Longping, the "father of hybrid rice",and his team underwent its first public yield（产量）monitoring from Monday to Tuesday and achieved high output. The final yield of the tested variety, G3﹣1S/P19, came to 1046.3 kg per mu （about 667 square meters）, based on two plots of land in Qingzhu Village under the city of Hengyang in central China's Hunan Province.

"Some previous high﹣yielding hybrid rice varieties in China took 160 to even 180 days from sowing to harvesting, while the figure was shortened to around 125 days for the new variety. This is one of the most important characteristics of the third﹣generation hybrid rice that can reduce the use of pesticides and fertilizers, thus reducing cost and improving production efficiency. " said Qian Qian, the deputy director of the China National Rice Research Institute.

Unlike the previous two generations that required a large amount of water and fertilizers as well as demanding growing conditions and technological support, the third﹣generation hybrid rice is easier to be cultivated by ordinary farmers. So the soil, altitude and climate of the test site were not "ideal conditions" carefully selected beforehand but were close to the paddies of ordinary farmers.

Nowadays, China's average yield of rice is about 500 kg per mu. Ordinary farmers can produce 600kg to 700 kg of rice per mu by growing some excellent second﹣generation hybrid rice varieties. However, under the same planting conditions and environment, the yield of the third﹣generation hybrid rice could reach 800 kg per mu. China now feeds around 20 percent of the world's population with less than 9 percent of the world's arable（可耕种的）land.

At present, Yuan's team has nine third﹣generation hybrid rice combinations under trial, which are expected to achieve commercial seed production in the following three to four years and hope to apply the technology into the research of sea rice. The third﹣generation hybrid rice has the comprehensive strength to promote a greener and more sustainable development of China's rice production with higher quality and yield.
